This content is available immediately and for nothing to Elite subscribers, with non-Elite subscribers able to download the content for a price at a later date. No news on either of those specifics yet though I'm afraid. If you're not an Elite subscriber, it's worth knowing that Activision are planning on hooking Modern Warfare 3 players with at least 20 new DLC items over the next nine months. If you're planning on sticking around online for that long, it may be worth the investment.
